8 Claims.

This invention relates to safety razors of the magazine type and consists in improvements in structure and operation which result in greater accuracy, reliability, freedom from jamming and 7 general convenience to the operator than has been found in implements of this class heretofore available. It also results in a simplified mechanism which may be manufactured and assembled to good advantage in quantity production.

An important feature of the invention consists in a one-piece detachable blade-retaining member which is made of resilient material and shaped to the contour of the razor head so that it may be assembled by being sprung upon the head and thus held in position as part of the razor assembly. Besides eliminating the necessity for fastening devices, this construction greatly facilitates the assembling operation and thus reduces the cost of the razor.

Another feature of the invention consists in a blade locating or positioning member of spring material presenting blade stops at opposite ends of the stationary guard which are effective to position the blade accurately upon the blade seat of the razor. These stops may be conveniently retracted to release the blade by the presentation of the magazine holder when it is desired to re place the blade.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawings, in which:

The razor herein shown is designed to take a fiat single-edged blade 39 of the type shown in Figs. 7 11 and 15, that is to say, a narrow rectangular blade having end notches 3i and spaced rectangular apertures 32 and 33 in its body. The razor itself comprises a handle l0 threaded at its upper end into a solid head II which may be die-cast or otherwise fashioned and which includes as an integral part thereof an outwardly or forwardly projecting flange l2 provided at its inner edge with a longitudinal shoulder and constituting a fiat elongated blade seat in the razor. The body of the head I l is elongated transversely and rounded at its upper and lower rear edges and its flange portion 12 is extended forwardly and downwardly beyond the blade seat and serrated to form a stationary guard l3 which, in the assembled razor, is disposed beneath the shaving edge of the blade. A spring retaining or holddown member 54 is curved to conform to the contour of the head i l and provided with a flat forwardly extending flange which co-operates with the blade seat to hold the blade in place by yieldingly engaging the same. The hold-down member it may be forceably sprung out of enagement with the head H but otherwise it reinainsin contact with the head as a permanent shoulder and thus to position its shaving edge properly and. safely with respect to the fixed guard it. To this end, the ends of the guard l3 are notched and the front and lower faces of the head I! are recessed to receive a forked member 55 of resilient sheet metal. This member, as best shown in Fig. 8. comprises a base flange 34 which is perforated for the passage of the threaded stem of the handle l0 and shaped to fit into the corresponding recess provided in the under face of the head ll. The base flange 34 of the memr iii merges into an upstanding portion which fills a wide shallow recess bounded by diverging end Wall provided for that purpose in the front relation thereto. end and is shaped to enter the channel I8 of face of the head I I as shown in Fig. 2. This upstanding portion of the member I5 merges in turn into a pair of diverging arms terminating in the upstanding blade-engaging stops I6. These stops are so located as to embrace the guard I3, engage the outer corners of the blade edge and normally press the blade inwardly to maintain its back edge in contact with the shoulder of the blade seat Hi. The main or center portion of the member I5 as shown in Fig. 8 is bent inwardly to form a substantially horizontal angular arm I! having a down-turned wall or flange 29 providing a contact face disposed midway between the blade stops I6 and substantially in alignment and above the perforation in the base flange 34 of the member.

The head I i is provided with a straight shouldered channel or passage I8 extending longitudinally through it from side to side and disposed substantially at right angles to the blade seat. The front wall of the head is cut-out centrally providing an opening or transverse passage to receive the arm ll of the spring blade-retaining member and permit its oblique wall 29 tostand in the channel I8 as shown in Figs. 1 and 3; that is, the internal transverse passage extends from the longitudinal passage I8 and opens into the front face of the head, being covered by the member I5. As will be presently described the forked blade retaining member may be sprung forwardly to release the blade by a prying member forced into the channel I8. It will be understood that the blade seat provided by the flange I2 is open at both ends and that a blade may be presented in shaving position by being introduced endwise into the razor beneath the yielding flange of the hold-down member [4 while the blade stops l6 are temporarily retracted or moved away from the inner shoulder of the blade seat. The member I5 may be formed by bending a sheet metal blank and in assembling the razor it is necessary only to drop it into the recess provided for it in the head, pass the threaded stem of the handle through the perforation in its flange and tighten the handle. The razor thus far described is a complete shaving implement and does not require a blade magazine although it is most effectively employed in co-operation with such a magazine.

The magazine mechanism herein disclosed includes a holder, best shown in Figs. 12 and 14,

'and comprising an elongated sheet metal member having a flat guideway 20 defined by parallel inturned edge flanges 2| and 22. The rear end of the guideway is closed by spring detent 23 which may be temporarily depressed below the level of the guideway, as shown in Fig. 14, when it is desired to introduce or remove the magazine but which otherwise prevents accidental disengage- The guideway is formed parallel to the guideway but disposed in edgewise The finger 24 has a bevelled the razor, being sufficiently long to locate the holder positively with its guideway in registration with the blade seat provided by the flange S2 of the razor head. The finger 24 is provided on one face with an elongated rib 25 which travels in the reduced portion of the channel when the finger is inserted therein and is the part of the finger which comes in actual contact with the oblique face 29 of the stop controlling arm I1 already referred to. The finger 24 is also provided in its lower edge with a shoulder 26 which'en- -gages the end face of the head II and to determine the endwise position of the holder when operatively connected to the razor head. The bottom of the holder is provided with a pair of rectangular openings through which project spring detents 21 and 28, one located in advance of the other. A short section IQ of the flange 22 is separated from the rest of the flange and pressed together to form a solid stop for limiting movement of the magazine toward the left.

The magazine itself comprises a rectangular box 4|] of sheet metal having at its one open side a pair of spaced parallel flanges 4| made by folding the sheet material of the magazine so that it presents two outwardly extending ribs, shaped to run beneath the inturned flanges 2| and 22 of the guideway of the holder, and two inturned blade confining ribs. The inner edges of the flanges 4| are spaced apart so as to expose the center section of the lowermost blade in the magazine with its apertures 32 and 33. The flanges 4| are slightly shorter than the full length of the magazine thus leaving short open spaces adjacent to the front and rear walls thereof. Both the end walls of the magazine are provided with inwardly projecting vertical ribs 35 shaped to fit the end notches 3| ol the blades and thus to hold the sharp edge thereof out of contact with the wall of the magazine and prevent them from being dulled when discharged. The front end Wall of the magazine is provided with a spring feed dog 42' which normally projects forwardly and downwardly and is adapted to engage the inner aperture 33 of the lowermost blade in the magazine as will be presently described. Within the magazine is provided a leaf spring 43. This is tained therein, holding the lowermost blade always in contact with the flanges 4|. The magazine may be loaded by inserting blades from either end above the flanges 4|, meanwhile pressing them inwardly to deflect the leaf spring 43.

When it is desired to replace a blade in the safety razor with the assistance of the magazine mechanism above described the holder is brought into the relation with respect to the razor as suggested in Figs. 4 and 5, that is to say, the finger 24 is aligned with the shouldered channel Ill. The finger 24 is then introduced into the channel, as shown in Fig. 6, and the holder is moved to the left until arrested by engagement of the shoulder 26 with the right-hand wall of the razor head, as shown in Fig. 7. In this movement, the rib 25 on the finger engages and outwardly displaces the stop controlling arm springing the member I5 outwardly and moving the blade stops I6 forwardly as indicated in Fig. '7 so that the blade 30 is held in place upon the blade seat only by the yielding engagement with the retaining member l4.

The magazine 40 is now reciprocated in the guideway 30 from right to left and back again from left to right. In the movement of the magazine toward the right the forward detent 21 engages the forward aperture 32 of the lowermost blade in the stack and holds it stationary as the magazine completes its movement back to its rear or right-hand position. In this position, moreover, the feed dog 42 is brought into registration with the rearmost aperture 33 of that blade, all as represented in Fig. 9 of the drawings. The magazine is now moved again toward the left and the blade 30 is advanced by the feed dog 42 out of the guideway 23 and into the razor for about one-half its length, displacing the used blade by pushing it ahead and partially out from the left-hand side of the razor. The magazine is shown in this condition in Fig. 10. The maga zine is now moved again toward the right, as best shown in Fig. 11 leaving the blade half exposed in theguideway 20 and half inserted into the razor. In this movement of the magazine the blade is held stationary in the guideway 20 by the rearmost detent 28 in the bottom of the guideway which engages the rear end of the blade. Finally the magazine is moved again toward the left and in this movement the blade which is lowermost in the magazine acts to advance the half exposed blade pushing it fully into the razor, locating it in shaving position and fully ejecting the used blade. The holder is then detached by withdrawing the finger 24, whereupon the stop controlling arm I! is released by the rib 25 and the blade stops I6 move inwardly engaging the corners of the blade and seating it accurately upon the blade seat, ready for shaving.

From the foregoing description it will be apparent that the magazine holder with a magazine of blades may be easily connected to the razor or detached therefrom at the option of the user and that when the holder has been so attached a new blade may be presented in shaving position by imparting two complete reciprocations to the magazine in the holder. The first reciprocation inserts the new blade half-way into the razor where it is held securely in place by engagement with it of the retaining member l4 and also by the detent 28. --The blade therefore is secured against displacement during the first half of the second reciprocation of the magazine. In the final movement in this second reciprocation of the magazine the new blade is fully seated and the old blade fully ejected. Blades may be supplied in this manner as long as the supply holds out in the magazine. When the magazine is exhausted it may be removed from the holder by depressing the detent 23, thus permitting the magazine to be drawn out of the guideway 20. The magazine may be then conveniently refilled or if the blades are dispensed in the magazine a new full magazine may be slipped into the guideway.
